How the melt value is worked out
Melt value is the pure gold in the coin multiplied by the spot price. We use the coin's standard minted weight; worn coins weigh slightly less.
-
16.25 g × .917 fine ÷ 31.1035 g per troy oz = 0.4791 troy oz
0.4791 troy oz × $3,996.90 spot = $1,914.86
Melt value vs. collector value
Melt value is a floor, not a price. Better dates, coins with mint luster and graded coins often sell well above melt; key dates and rare varieties can be worth many times more. Check the date and mint mark before selling a coin for its metal.
